Dynamic Characteristics And Experimental Study On Non - Contact Information Crossing Of Fuze

For the design of Fuze Information Interaction System based on Magnetic resonant coupling theory in dynamic enviroment,in order to solve the key problem of the non-coaxial and dynamic magnetic resonant coupling transmission system, theoretical and experimental research are carried out.First, magnetic coupling resonant circuit calculation model is established,the power transfer expression is derived for the analysis of the load and the coupling coefficient with mutual inductance coupling theory; For the study of the resonant coil non coaxial transmission characteristics, mutual inductance coefficient is calculated for the analysis between it and lateral offset with the theory of electromagnetic field; According to the requirement of the system, the modulation mode and the way of encoding are confirmed.Then according to the theoretical results, electromagnetic simulation experiment is carried on to verify the feasibility of non-coaxial resonant transmission system. The index of dynamic transmission system based on capacitance charging time is established for analysing the relationship between the charging time and the relative moving speed of the resonant coil.The information transmission model is established and its impact to power transfer is also analysied.Finally, according to the theoretical study and simulation research,building the Fuze Information Interaction Circuit System; In order to test the influence of circuit parameters on the system transmission rules, static experiment, dynamic simulation and range test are carried out using the prototype, experimental results and the theoretical results are in good agreement.The results of this study for the dynamic environment based on magnetic resonance coupling of Fuze Information Interaction System design provides theory and design reference, laid the foundation for the further application of this technology.
